MAC, WWN, and Serial Number management
You must verify that VC Domains within a network have unique MAC addresses, WWN addresses,
and serial numbers. Adding a VC Domain to a VC Domain Group or creating a VC Domain Group
does not verify that the profiles in a VC Domain use MAC or WWN addresses allocated in the
VCEM external address pool. You can overwrite the external addresses to become in use status.
To prevent external addresses from use in VCEM, add the addresses to the exclusion addresses
pool. If you plan to add the VC Domain back to VCEM, then you must also remove these addresses
from the exclusion addresses pool.
Duplicate MAC and WWN address assignments
Using VCEM 6.2 or 6.2.1 may result in duplicate MAC and WWN address assignments. This will
occur if a VC profile edit fails when removing iSCSI or FCoE connections via the VCEM Graphical
User Interface (GUI). The VCEM 6.2.2 or later upgrade contains a critical fix and is strongly
recommended to prevent this issue.

Unauthorized error when trying to access the VCEM home page
VCEM requires the CMS to be correctly registered in the DNS. Make sure Systems Insight Manager
can correctly discover the CMS. You might experience an unauthorized error page when trying
to access the VCEM home page if the CMS is incorrectly registered in the DNS.
To correct this issue, register the CMS in DNS or add the CMS hostname to the Windows hosts
file.
A job appears with Failed status
A job might fail for several reasons. For more information about the reason of job failure and how
to correct the issue, see the job details:
1. From the VCEM home page, click the Jobs tab.
2. Locate the job, either by its ID or its name.
3. For detailed information about the job and how you can resolve the issue, click the task name
of this job.
4. (Optional) Job details might appear to be truncated when the text exceeds 256 characters.
If this occurs, to view the full job details, go to Systems Insight Manager left navigation
panel→Events→Shared→VCEM Events.
Enclosure has two Onboard Administrators, and one fails
If an enclosure has two Onboard Administrators with redundancy and one fails, then the redundant
Onboard Administrator might take several minutes to take over. Before performing any operations
to the VC Domain, wait until the Onboard Administrator has failed over. Perform an Systems Insight
Manager discovery to rediscover the new Onboard Administrator IP address. If it is not rediscovered
then see the HP BladeSystem c-Class Onboard Administrator User Guide.
VCEM is prompting for Onboard Administrator credentials on a configured
VC Domain
VCEM might prompt for Onboard Administrator credentials on a VC Domain that has already
been configured where the Onboard Administrator has been imported and discovered. This issue
occurs when a backup VC is discovered or if a failover of a VC Module occurred in a redundant
